How to split the screen in 2 parts Xiaomi Redmi 9

Xiaomi smartphone owners often face the need to use multiple apps at once. The Redmi 9, despite its budget-grade, features a powerful processor and ample RAM to comfortably work in split-screen mode. This feature, known as Multitasking, makes the device an effective tool for work and entertainment.

Imagine watching a training video while taking notes, or texting while reading news, all made possible by Split Screen. However, in the MIUI shell, activation of this mode may be different from standard Android, which often raises questions among users. In this article, we will discuss in detail all the ways to activate and configure window mode.

First of all, it's worth noting that split-screen is built into MIUI by default. You don't need to install third-party apps or get root rights. However, it needs to be updated to the current version to work properly. Old firmware builds may contain bugs that prevent multi-windows from running smoothly.

Preparation of the device for operation in multi-window mode

For split screen to work consistently, you need to make sure there is free space in RAM. Redmi 9 may have difficulty rendering two heavy applications at the same time if the system is overloaded with background processes.

It is also important to check the display settings. If you have "enlarged text" mode on or changed the screen resolution, the window interface may not display correctly. Standard parameters 1080x2340 are optimal for splitting the display area in half without distortion.

• 📱 Make sure the version MIUI at least 11 (check the About Phone menu).
• 🚀 Close background applications through Task Manager for release RAM.
• 🔋 Charge the device to at least 20% as the two applications accelerate the discharge.

⚠️ Note: On devices with 3GB or less of the same time, two “heavy” applications (e.g., the navigator and the game) can lead to a strong heating of the case or forced closure of one of the processes.

How to activate through the menu of recent applications

The most common and convenient way to start split-screen mode on Redmi 9 is through the task menu, which requires no deep immersion in the system settings and is available immediately after unlocking the device. The algorithm is intuitive, but has its own characteristics depending on the type of navigation.

First, you have to run the first app you want to see at the top of the screen, then fold it up and launch the second app. Now that both processes are active, call the menu of recent apps, depending on the navigation settings, this is done by swiping from the bottom up with a delay or pressing the "Menu" button.

In the list that opens, find the first app card. In the upper right corner of the card (or if you press it long, depending on the version of MIUI), an icon that resembles two rectangles or arrows will appear. Pressing this item will activate Split Screen mode. The screen will split, and the system will prompt you to select a second application from the list of recently used ones.

Using the sidebar for quick access

The MIUI shell offers a more advanced window management tool, the sidebar, which is a floating menu that allows applications to run in split-screen mode in one click without interrupting current activity. To use this feature, it must be pre-activated in the system settings.

Go to Settings → Special features → Sidebar. You need to turn on the activation switch and select the applications that will be displayed in the Quick Access menu. After turning on the side of the screen, a translucent bar will appear that calls the toolbar.

When you're in any app, just call the sidebar and tap the app icon, and it opens in a floating window that can be stretched halfway across the screen, making it a full-fledged split mode, which is especially convenient for quick response to messages or calculator checks.

Customizing the behavior of windows and size management

Once the split-screen mode is activated, the user has full control over the proportions of the windows. On the 6.53-inch Redmi 9, it is important to properly allocate the space so that the content is read comfortably. The boundary between the windows is regulated by simple drag and drop.

The black stripe separator between the two active windows is interactive. Tap it and pull it up or down to change the area ratio, and you can prioritize the top window by leaving the bottom one with just a narrow strip, or you can make the windows equal.

It's important to know that not all applications support flexible resizing. Some programs, especially older ones or full-screen optimized ones, may require a fixed aspect ratio, and in such cases, the system will automatically select the optimal size and it will not be possible to change it.

Features of working with floating windows

An alternative to Xiaomi's classic split screen is the floating window mode. Unlike static splitting in half, the floating window can move freely across the display and change its size regardless of the main application. This creates a Picture-in-Picture effect, but for any program.

To float the app, run it through the sidebar, the window will open on top of the current content, you can drag it over the top edge, resize it around corners, or roll it into a narrow strip on the side, which is ideal for watching video while you're texting.

However, it is worth considering the load on the processor. Simultaneous operation of the main application and the floating window requires more CPU resources. If you notice twitching images or input delays, it is better to close the unnecessary processes.

⚠️ Warning: When operating in floating window mode, sound can only be played from one application at a time. Running a video in a second window often puts the former on pause.

Problem Solving and Application Compatibility

Not all apps in the Google Play store work properly in split-screen mode. Developers can programmatically prevent their software from running in multi-window mode for security or interface reasons, and in such cases, you will see a message that the application does not support this feature.

A common problem is incorrect keyboard display. When typing in the bottom window, the virtual keyboard can override the content of the top window. To solve this problem, try resizing the windows by making the bottom one bigger, or use an external keyboard.

• 📉 Social networks (Instagram, TikTok) often block screen splitting.
• 🎮 Anticheat games can be forced to close when changing windows.
• 💳 Banking apps can restrict functionality in Split Screen mode for security reasons.

If the app doesn’t start in the second window, try updating it through the store or check for system updates in the Settings menu → About Phone → MIUI version.

💡

For some applications that don’t formally support screen splitting, you can use hidden debugging mode, but it requires a PC connection and use. ADB-commands that are not recommended for ordinary users.

Completion and withdrawal from the regime

To exit split-screen mode, you just drag the center dividing line completely up or down to the end of the display. One of the applications will close, and the other will occupy the entire screen. This is the standard closing mechanism that works in all versions of MIUI.

You can also just roll one of the windows or close it through the recent task menu, and the system will automatically stretch the remaining application over the entire area available, no additional steps are required to save data, and the state of the applications is saved.

Keep important data regularly.

💡

The Redmi 9’s split screen mode is a powerful productivity tool, but it requires smart memory management to avoid lag.
